To all whom 'it may concenbi Be it known that I, WILLIAM RU'LISON,citizen of the United States, residing at J ohnstown, in the county ofFulton and State of New York, have invented certain new and usefulImprovements in Apparatus for Delivering Measured Quantities of Ma;terial; and I do hereby declare the following to be a full, clear, andexact dwcription:

of the invention, such as will enable others skilled in the art to whichit appertains to make'and use the same.

This invention consists in the novel features hereinafter described,reference being had to the accompanyingv drawings which illustrate oneformin which. I have contemplated emhod my invention and the inventionis fully disclosed in the following specification and claims.

This a plication is a division of my former a p 'cation for LettersPatent of the Unite States for im rovements in b 3g filling and sealingmac e, filed July 13,

ferred to.

1908, and given Serial Number 443,241 and covers specifically themechanism for delivering measured quantities of material, therein shownand described. l

Referring to the drawings: Figure 1 is a side elevation of a device fordelivering measured quantities of material embodyin my invention.view-of the same. Fig. 3 is a view similar to Fig. 1 showing theopposite side of the apparatus. Fig. 4 is a detail sectional view 0 apart of the measuring device somewhat enlarged and the adjusting devicefor varying the capacity thereof. Fig. 5 is a transverse sectlonal viewon line .5'5 of Fig; 4. Fi .6 isaviewsimilartoFig.1,apart ofthe opperbeing broken away and showing a modification. F 7 is-a detail view ofthe'leveling device or ail shown in Fig. 6. 'In the drawings I haveshown in 1mproved measuring and delivering devlce iii the form bestadapted for use in connection with -my improved bag filling machine,shown in my former application, before re- In the-drawings, in which theseveral parts are indicated by numerals, 5 represents a hopper forcontaining the material,

and which is supported in any suitable man- Specification of LettersPatent.

just Fig. 2 is a vertical sectiona Patented 001;. 5, 190a. Divided andum application ma I ovember her, as by braces '6, 6 extending the frameof a bag filling'machine.

Thehopper is provided with an a erture 8 on one side communicating wit asupply pipe 9, through which the material 1s introduced, and the supplyaperture 8 is' controlled by asliding gate 10, operable from theinterior of the hopper by means of a projection 11. The pro ection 11also referabl extends through a slot 11" in the Back of t e hopper toenable the to 10 to be adjusted from the outside i desired. The ate 10is held frictionall in-its ade positions. The front wa per is providedwith a swingingdoor 5" covering an aperture through Whlch access can behad .to the interior to adjust gate 10, or the measuring cupshereinafter described. I also refer to provide a transparent panel 5" int e hopper as shown so that thebperator can -see if material -is in thehopper. The hopper is also provided with a downwardl dlrected tangentialdischarge spout 12, w ch is preferably surrounded by an exterlor ca 13,connected an-air pipe 14, communicating with an air exhaustof thehopside -walls of the ho perv and is provided with a plurality of ra alarms 16, two being shown, carrying at their outer ends adjustablemeasurin scoops or buckets 17, second to the ends 0 said arms by straps18,.or in any otherdwired way. The scoops'or bucks ets are best shown in2, 4=- and5 and consisteach of a cylindrical shaped vessel closed atoneend and having its walls projecting farther on the side ad'acent to theshaft than at other portions. ach scoop is preferably rovided' w'ith afalse bottom .19, adjustable the ca acity of the yessel, andthe screw 20is .pre erably provided with afriction s or brake 21 Figs. i and 5)which against the wall of the vessel, and holds the screw in itsadjusted position. Each of said scoops or m receptacles, as will beseen, has its mouth facing at an 2:151: (and less) to a a1 line in thiscase at right passing ymeans of a screw 20, to vary through the axis .ofrotationnf the shaft 15. I Y

The shaft 15 is provided with suitable mechanism for impartin rotar'motion thereto, in the direction in icated y the arrow in Fig; 2, and Iprefer to have said thereto.

The material to be measured and delivered is supplied to the tube 9,leadin to the hopper 5 continuously or at interva s, in any desiredmanner, and finds its way by gravity, into the bottom of the hopper,being regulated by the gate 10." The rotation of the cups l7l7 causesthem to fill themselves Yes of the measurin they pass through the lowerpart of the hopper and to'discliarge vmeasured uantities of the materialthrough the disc arge aper-. 25"

The transparent panel which, as shown, extends from the lowermost pointof the hop er, upward enables-the operator to see the evel of thematerial in the hopper at all times, and by'opening the door 5the'operator may ad ust the capacity of the cups by turning the screws20, and may also adjust the gate 10 as previously described.

An dust'cont'ain ed 1n the material when it is elivered by the spout 12,will be drawn into the passage 13, and removed by suction.

through pipe 14.

thebags with a measured quantity of a material which is apt to pile upat the mouth cups or vessels and cause slightly unequ amounts to bedelivered thereby, I employ the device shownin-Figs.

'6 and 7 to equalize the uantity in the-measuring cups or vessels as atas ossible. This conslsts of a scraper or leve er 190 inthe form of abail mounted on a rock shaft 191 extending through the ho per-(here"num'- 2 bered 5) and. rovided wit 'an arm 192 connected pivota ywith' a bar 193 having a forked end-194 to engage the shaft "v to guideit, and astud'or roll 195 to engage a ouble cam 196 on the said shaft, as'prin 197 servingto retract said bar 193 and-hold the roll inengagement with the cam.

each of the'ineasuring' cups orvessels asses the bail 190 the latter isoperated by t e action of the spring and cam to sweep over the top ofthecup,'. and scrape o'flF-any surplus by adjusting the capacity of thecups as bematerial which falls to the bottom of the, hopper 5, thusinsuring an even feed of the material which can be accurately regulatedn the drawtary device within the hopper, a measurin receptacle carriedthereby havlng its mout receptacles and having a fore described, saidcupsbeing identical in corislguction with those previously described.

o notdesire to be limited to the exact details of construction hereindescribed and shown as slight variations may be made therein withoutdeparting from the invention. 1
